Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
For the efficiency that improves the demonstration mainboard procedure and burn record, the utility model provides a burn record subassembly.
Referring to fig. 1, in an embodiment, the present invention provides a recording component including a memory interface 10, a recording output terminal 20, a trigger component 30 and a control circuit 40.
Wherein the memory interface 10 is used for connecting with a memory.
The burning output terminal 20 is used for connecting with a memory chip of the display mainboard.
The trigger component 30 is used for outputting a burning trigger signal when triggering.
And the control circuit 40 is electrically connected with the memory interface 10, the burning output end 20 and the trigger assembly 30 respectively, and is used for reading the pre-burning program in the memory and burning the pre-burning program into a memory chip of the display mainboard connected with the burning output end 20 when receiving the burning trigger signal.
In this embodiment, the number of the memory interfaces 10 may be one or more, and the types of the plurality of memory interfaces 10 may not be uniform, such as a USB interface, a SATA interface, an m.2 interface, an ATA interface, and the like, and are used to plug and unplug different types of external memories, such as an external memory like a USB disk, a mobile hard disk, and a solid state disk. So, maintainer is using the utility model discloses burn the subassembly and burn when writing into the demonstration mainboard of difference, perhaps when burning into different programs to same money demonstration mainboard, only need the replacement to insert the same money memory that has saved different burn-in and write into the program, perhaps the memory of the different grade type of having saved difference and burning program, just can realize to the program for showing the mainboard burning into different versions, improved maintainer's convenience in the burning work after sale effectively, reduced the preparation time and the switching time of burning into different programs, improved the efficiency of burning into to showing the mainboard program.
In this embodiment, the burning output terminal 20 may be a burning pin, a burning probe, and the like, and is used to connect to a data pin of a memory chip on the display motherboard, so that the control circuit 40 can write the burning program into the memory chip of the display motherboard.
In this embodiment, the trigger component 30 may be a key, a toggle switch, or other devices, and when a maintainer needs to burn a program on a memory chip of the display motherboard, the maintainer may press the key or the toggle switch to enable the trigger component 30 to output a burning trigger signal, where the burning trigger signal may be a high level signal or a low level signal. After receiving the burning trigger signal, the control circuit 40 can communicate with the memory connected to the memory interface 10, read the data stored therein and burn the data to the memory chip of the display motherboard through the burning output terminal 20.
In this embodiment, the control circuit 40 may be implemented by a main control chip, such as a main control chip of an MCU (microprogrammed control unit), a DSP (Digital Signal processing) chip, an FPGA (Field Programmable Gate Array) chip, or the like. When receiving a burning trigger signal with an effective high level or an effective low level, the main control chip establishes communication connection with the memory accessed to the memory interface 10 according to a certain communication protocol, such as an SPI communication protocol, a serial communication protocol, an I2C communication protocol, a USART communication protocol, and the like. And then, the main control chip reads the pre-burning program stored in the current memory, performs certain signal processing on the read pre-burning program according to a communication protocol corresponding to the storage chip of the display mainboard, and burns the pre-burning program into the storage chip of the display mainboard, so that the processes of erasing, burning, checking and the like of the storage chip of the display mainboard are realized. So, when maintainer carries out follow-up upgrading to showing the mainboard, can directly burn the storage chip that shows the mainboard, need not to burn the main control chip that shows the mainboard again to and need not to burn through the ware of burning that uses and main control chip to correspond, and directly adopt SPI communication protocol to carry out data transmission to the storage chip and compare the speed that the computer burned faster, thereby improved the speed of burning the procedure effectively.

Meanwhile, when in burning, a maintainer does not need to perform burning operation through a computer and a burner corresponding to the main control chip, and does not need to install a corresponding driving program on the computer, so that the convenience and operability of burning work are effectively improved.
In the actual later maintenance and upgrade process, the states of the memory chips of different display mainboards may be different, and the internal storage amount may also be changed by the current state of the memory chip, for example, a small part inside the memory chip is damaged, which may result in a reduction in the storage amount. Therefore, when the pre-burning program is burned into the memory chip of the display mainboard, the pre-burning program may be larger than the capacity of the memory chip of the display mainboard. If the maintainer directly performs the burning, the failure of the burning may be prompted after waiting for a period of time, for example, 30S is required for normal burning, and the failure of the burning may be prompted when an excessively large program reaches 25S, which causes waste of burning time and reduces burning efficiency.
Referring to fig. 2, in an embodiment of the present invention, the burning component further includes a display component 50.
Wherein the display assembly 50 is electrically connected to the control circuit 40. The control circuit 40 is further configured to detect a data amount of the pre-burning program in the memory when receiving the burning trigger signal, and stop burning and control the display module 50 to output a warning signal indicating that the burning fails when detecting that the data amount of the pre-burning program in the memory is greater than a preset data amount.
Specifically, the control circuit 40 may output a data amount inquiry signal to the memory when receiving the burst trigger signal. When the memory receives the data amount inquiry signal, it will detect the data amount of the pre-burning program and output the corresponding data amount signal to the control circuit 40. When the data size of the pre-burning program is larger than the preset storage value according to the data amount signal, the control circuit 40 stops burning and controls the display component 50 to display that the capacity of the current storage chip is not enough, the display component 50 may be a display screen, such as a TFT screen, an LED screen, an OLED screen, etc., and the control circuit 40 may display "the capacity of the storage chip is not enough" on the display screen to prompt the user.
Therefore, the utility model discloses burn record equipment just can compare program size earlier before beginning to read the procedure in the memory, prevents to lead to maintainer to have wasted the burning record time inadequately because the size that shows the storage chip of mainboard to the efficiency that shows the mainboard procedure burning record has been improved.
